BACKGROUND Hypothermia is a major cause of deterioration and death in the neonatal period. Temperature deviations are key signs of illness. OBJECTIVE To determine normal patterns of temperature variation in newborn babies and the influence of external factors. METHODS Abdominal and foot skin temperature were continuously recorded in 27 healthy full term babies during the first two days of l...

The objective of this research was to determine if whole-body shearing would effect gross thermoregulation in alpacas. Eight mature, intact male alpacas were randomly assigned to one of two groups and maintained in outdoor pastures with adequate artificial shade from June through August (summer climate) in east central Alabama, USA. Group one animals (N=4) were sheared to remove all fiber to wi...

Chester White pigs weighing 65 to 70 kg bearing surgically implanted catheters were placed under a surgical plane of anesthesia and subjected to programmed increases in dry bulb and dew point temperatures from 27C at a rate of 5 ~ per hour (70 to 80% relative humidity) until heart and respiratory action ceased. Changes in plasma adrenocorticotropin (ACTH), adrenocorticoids and growth hormone le...

The goal of this work was to develop and validate a neuro-fuzzy intelligent system (LOLIMOT) for rectal temperature prediction of broiler chickens. The neuro-fuzzy network was developed using SCILAB 4.1, on the ground of three Departamento de Engenharia, Universidade Federal de Lavras (UFLA), Caixa Postal 3037, Lavras/MG, Brasil [email protected] [email protected] [email protected] Des...

Previously we have shown in dogs that tibial bone marrow and s.c. tissue temperatures are lower than rectal temperature during the plateau phase of whole body hyperthermia with the use of a radiant heating device. In an attempt to increase thermal dose to these sites during whole body hyperthermia, we applied insulation to an extremity prior to the plateau phase of heating. We found that extrem...

To test the hypothesis that segmental thoracic extradural block causes sympathetic denervation caudally beyond dermatomes rendered analgesic, we have measured regional skin temperatures in six conscious dogs after upper thoracic, mid thoracic, and lumbar extradural injection of 0.5% bupivacaine 0.5, 1 and 2 ml cumulatively (total dose: 3.5 ml) given at 45-min intervals. Dogs were studied at con...

The efficacy of a Gamgee-lined hat in reducing the rate of fall in rectal temperature of infants during the first 30 minutes of life was studied. The trial, which included 211 infants, was randomised, prospective, and controlled. One hundred and seven infants were exposed to overhead radiantheaters. Of these, only 30 had normal deliveries, so the analysis was confined to the infants who were no...

The lack of an effective treatment for endotoxemia causes high mortality rates in affected animals. Forty clinically healthy 1-year old Iranian fat-tailed ewes were assigned randomly into 8 experimental equal (n = 5) groups, comprising Insln 1.5, Insln 3, Insln 6, Insln 9, Insln 20, Dexa, Flnx and Control. Lipopolysaccharide from E. coli serotype O55:B5 was used to induce endot...

A system has been established for continuous recording of rectal and body surface temperatures in conscious, chair-restrained rhesus macaques. Diurnal changes in rectal temperature and body surface temperatures of head, back, abdomen, and inner thigh were recorded for 24 hours under conditions of intermittent or constant light. When lights were on for 8 hours (0800 to 1600 hours) and off for 16...
